Arbitrum 生态永续合约去中心化交易平台 AFX Trade 遭遇安全事件。安全公司 Blockaid 表示,平台运营的 USDC 托管桥被攻击,损失约 2415 万美元。AFX 随后暂停桥接服务,并启动事件处置流程。

被盗资金已转至以太坊

AFX 表示,具体攻击路径仍在调查中。链上安全机构 PeckShield 称,攻击者已将被盗 USDC 跨链转至以太坊,并兑换为 12,468 枚 ETH,目前资金集中在一个地址中。

平台称,受影响范围目前仅限于 AFX 自行运营的托管桥,交易基础设施、主网系统以及 Arbitrum 网络本身未受到影响。AFX 还表示,正与生态合作方及安全机构合作追踪资产流向。

Arbitrum 澄清原生桥未受影响

事件发生后,Arbitrum 联合创始人 Steven Goldfeder 出面说明,Arbitrum 原生桥“没有遭到任何形式的攻击或利用”,相关异常交易来自第三方协议,而非网络官方桥接设施。

这一表态意在将事故范围限定在单一应用层协议。若原生桥出现问题,影响通常会扩散至整个二层网络;而此次被攻击的是构建在其上的独立协议,风险相对局部。

AFX 向攻击者提出返还方案

AFX 在公开沟通中提出解决方案:若攻击者返还 70% 的资金,可保留其余 30% 作为“白帽赏金”。这一做法近年在加密安全事件中并不少见,部分协议会以此争取更高比例的资金回收。

这起事件也延续了 2026 年 DeFi 安全压力。报道提到,今年 DeFi 领域因攻击造成的损失已超过 8.4 亿美元。就在一周前,Arbitrum 上另一家永续合约平台 Ostium 也因预言机密钥被攻破而损失约 1800 万美元。
